Encontrar un dato y añadirlo a otra columna
Con parse_number sacaria todos los numeros de la columna,
pero lo que busco es sacar solo los que empiezan por AV y descartar el resto.
De todas maneras muchas gracias, le voy a dar otra vuelta.

Extracting numeric part from a string
Hi again,
I am struggling to extract the number part from below string :
"\"cm_ffm\":\"563.77\""
Basically, I need to extract 563.77 from above. The underlying number
can be a whole number, and there could be comma separator as well.
So far I tried below :
> library(stringr)
> str_extract("\"cm_ffm\":\"563.77\"",
